Look at Twitter, Facebook, Google, Instagram, even TikTok and many more tech companies are banned in China, what on Earth are the Americans' thinking? You guys are holy saints to think "with our open door policy will one day China be democratic and liberal like us" ?
Probably the Xi JingPing and his comrades are laughing at the Americans while watching the hearing, especially the congress member for discussing things so trivial while they would have probably already doing Machine Learning with the TikTok users.
Just ban TikTok, what takes you guys so long? You guys are not playing the same game as CCP, U.S.A being out-gamed not because not power but the speed on dealing with CCP.
